Oracle HTTP Server's WebLogic Plug-In MatchExpression is Merging Incorrectly (Doc ID 2484512.1)

Last updated on MARCH 29, 2022

Applies to:

Oracle HTTP Server - Version and later
Information in this document applies to any platform.


SSL Virtual Host is picking up mod_wl_ohs configuration from a non-ssl virtual host for a different port.
The expectation is that plugin configuration is local to the virtual host in which it is defined not global or applicable to other virtual hosts.

The issue can be reproduced at will with the following steps:

1. Configure mod_wl_ohs in virtual hosts as follows.
--Non SSL Virtual Host--

<VirtualHost *:<PORT1>>
   <IfModule weblogic_module>
      Debug All
       WLLogFile /<PATH>/mod_wl_nonssl.log
       MatchExpression *
       WebLogicCluster <HOSTNAME>:<PORT1>
       WLProxySSl ON

--SSL Virtual Host--

<VirtualHost *:<PORT2>>
   ...ssl things...
   <IfModule weblogic_module>
      Debug All
      WLLogFile /<PATH>/mod_wl_ssl.log
      <Location />
         SetHandler weblogic-handler
         SecureProxy On
         WebLogicCluster <HOSTNAME>:<PORT2>
      WLSSLWallet "<wallet>"

2. Test the access to the ssl virtual host eg https://<HOSTNAME>:<PORT2>/<URI>

3. Check the debug logs and find the request is routed to non ssl virtual host config.
